Mephistopheles Timeline and Summary

Mephistopheles first appears at Faustus's request and tells him that he can only be his servant if Lucifer agrees to it.
Mephistopheles re-appears, bringing word that Lucifer has agreed to Faustus's proposal if Faustus will sign his soul over to him in a deed of blood.
With the bloody contract signed, Mephistopheles teaches Faustus about the nature of hell and the devil, and about astronomy.
Throughout the play, Mephistopheles threatens Faustus with bodily injury, or calls on other spirits to help distract him, whenever Faustus considers God, heaven, or repentance again.
But he also does whatever Faustus wants him to, helping the magician conjure awesome things, perform great tricks, and taking the guy on a grand world tour.
Along the way, Mephistopheles manages to turn some peasants, Dick and Robin, into an ape and a dog, respectively.
After all their adventures, Mephistopheles confesses to Faustus that it was he who tempted Faustus away from God, by guiding Faustus's reading of the Bible the way he wanted.
Sneaky, sneaky.
